2 proportion z-test3. In a study done in Michigan, it was determined 38 (out of 62) poor children who attendedpre-school needed social services later in life compared to 49 (out of 61) poor childrenwho did not attend preschool.Does this study provide significant evidence that preschool reduces the need for socialservices later in life? 1. Explain the concept of a hypothesis test, and why it is used inresearch and science.2. Conduct a hypothesis test, by executing the following steps:a. Identifying the correct type of test.b.

2. A group of doctors at a specific hospital believes that the normal survival rate for patients with extensive burns will significantly increase with the use of new fluid plasma compresses. Before the new treatment, the survival rate for extensive burn patients at the hospital was about 40%. Using the new compresses, the hospital found that 48 out of 90 patients with extensive burns survived. Does this provide sufficient evidence for the hospital to try to market the new fluid plasma compresses to other hospitals? Answer this question using a = 0.05.
The president of a mid-sized state university has proposed lowering tuition rates in order to increase the school’s overall graduation rates (meaning she expects the two measures will be negatively associated with each other). She collects data on other similar universities, rating universities as “high” on tuition (above-average tuition costs) or “low” (below average tuition), as well as on their proportion of students who graduate in six years (categorizing with those graduating more than half of their students as “high” and those graduating fewer than half as “low”). A bivariate table with these data is below. Calculate the gamma and then write a sentence or two interpreting what it suggests about the relationship. Is there support for the president’s hypothesis? Graduation Rate by Tuition Rate Tuition Rate Graduation Rate Low High Totals Low 52 40 92 High 80 125 205 Totals 132 165 297
2.- The journal Behavioral Research in Accounting published a study of Machiavellian traits in accountants. Machiavellian describes negative character traits that include manipulation, cunning, duplicity, deception, and bad faith. A questionnaire by email was administered to a random sample of 700 accounting alumni of a large southwestern university; however, due to nonresponse and incomplete answers, only 198 questionnaires could be analyzed. Several variables were measured, including age, gender, level of education, income, job satisfaction score, and Machiavellian (“Mach") rating score. The research findings suggest that Machiavellian behavior is not required to achieve success in the accounting profession. a) What is the populatidn of interest to the researcher? Answer: Business accountants in the southwest Accountants in general Accounting alumni from this university Business alumni from this university b) What inference was made by the researcher? Answer: Accountants are always…
5. Dementia is a common mental health problem affecting those over 65. It is believed that of those that have dementia, 31% worsen in mental cognition. Acetyl-l-carnitine (ALC) is a drug that is used to determine if it will be beneficial with those with dementia. In a clinical trial, 98 patients are given the drug and their cognition is observed. Of the 98 patients, only 28 worsened. Construct a test to determine whether ALC decreased the proportion of patients who worsen from dementia. a) State the null and alternative hypotheses. b) Find the test statistic. Round to two decimal places. c) Find the p-value. Round to four decimal places. d) What is your decision at a 1% significance?
2. An article in the journal Applied Nutritional Investigation reported the results of a comparison of two different weight-loss programs (Liao, 2007). In the study, obese participants were randomly assigned to one of two groups and the percent of body fat loss was recorded. The soy group, a low-calorie group that ate only soy-based proteins (M= 3.1, s=0.55), while the traditional group, a low-calorie group that received 2/3 of their protein from animal products and 1/3 from plant products (M= 1.9, s=0.45). If sm1-M2 = 0.24, s²pooled = 0.25, n1 = 8, n2 = 10 is there a difference between the two diets. Use alpha of .05 and a two-tailed test to complete the 4 steps of hypothesis testing.
4. Straight As now, healthy later A study by Pamela Herd of the University of Wisconsin-Madison found a link between high-school grades and health. Analyzing data from the Wisconsin Longitudinal Study, which has tracked the lives of thousands of Wisconsin high-school graduates from the class of 1957, Herd found that students with higher grade-point averages were more likely to say they were in excellent or very good health in their early 60s. Does this mean people will live healthier lives if they increase their GPA? Explain.47
The Knight Foundation investigates whether high school students agreed with the statement that people should be allowed to burn or deface the American flag as a political statement. This question was asked in a survey of a representative sample of high school students in 2004 and also in a survey of a representative sample of high school students in 2014. Suppose that the sample size was 1000 in each of the two years. Data consistent with summary values given in the paper are summarized in the accompanying table. Is there convincing evidence that the proportions falling into each of the response categories were not the same for high school students in 2004 and 2014?
In an article in the Journal of Marketing, Bayus studied the differences between "early replacement buyers" and "late replacement buyers" in making consumer durable good replacement purchases. Early replacement buyers are consumers who replace a product during the early part of its lifetime, while late replacement buyers make replacement purchases late in the product's lifetime. In particular, Bayus studied automobile replacement purchases. Consumers who traded in cars with ages of zero to three years and mileages of no more than 35,000 miles were classified as early replacement buyers. Consumers who traded in cars with ages of seven or more years and mileages of more than 73,000 miles were classified as late replacement buyers. Bayus compared the two groups of buyers with respect to demographic variables such as income, education, age, and so forth. He also compared the two groups with respect to the amount of search activity in the replacement purchase process. Variables compared…
1. A developmental psychologist would like to determine how much fine motor skill changes for children from age 3 to age 5. He takes a random sample of 9 three-year old children and gives each a manual dexterity test that measures fine motor skill. He tests these same children one and two years later, when they are each four- and five-years old. Higher scores on this test indicate better fine motor skills. Is there a significant difference in the motor skills at these ages? Test with an α = 0.01 and show ANOVA SPSS output.
In an article dated April 24, 2005, USA Today reported on the 17th annual study on teen drug abuse conducted by the Partnership for a Drug-Free America. According to the survey of 8100 teens was Vicodin, with 19%-or about 8.2 million youths-reporting that they had used it to get high. OxyContin and drugs for attention-deficit disorder, such as Ritalin/Adderall, followed with 1 in 10 teens reporting that they had tried them. Is the statement about 19% of youths abusing Vicodin inferential or descriptive? Is the statement about about 8.2 million youths abusing Vicodin inferential or descriptive?
1. Pg 221 Good for the gut? Is fish good for the gut? Researchers tracked 22,000 male physicians for 22 years. Those who reported eating seafood of any kind at least 5 times per week had a 40% lower risk of colon cancer than those who said they ate seafood less than once a week. Based on this study, is it reasonable to conclude that eating seafood causes a reduction in the risk of colon cancer? Explain.44
Mood variation is related to photoperiod in some people, and the likelihood of depression increases in the winter months. As a result, people often assume that suicide rates increase in winter. A study in Finland (Valtonen et al. 2006) divided the year 1997 into equal halves and compared the number of suicides in “winter” (24 September to 19 March) and “summer” (remainder of year). Out of a total of 1636 suicides, 766 were in winter and 870 were in the summer. Based on these data, estimate the proportion of suicides that occurred in winter, assuming that the suicides were independent. Are the data compatible with a greater suicide rate in winter than summer, based on a 95% confidence interval?
